Contactors (Electromechanical)

CC225/4SAD24 application field and working principle

Contactors are electric control devices used for power control in electric drives. They are electromechanical switches capable of switching both large currents and high voltages. The CC225/4SAD24 is a popular type of contactor that is widely used in a range of industrial applications. This article provides an overview of the applications and working principle of the CC225/4SAD24 contactor.

The CC225/4SAD24 contactor is primarily used in applications that require large currents to be switched on and off. It is typically used in large-scale industrial systems, such as trilateral systems and feeders. Common applications include motor control, heating and ventilation, and electric lighting. The contactor is also used in industries such as mining, oil and gas, and maritime.

The CC225/4SAD24 contactor is composed of a main contact, an auxiliary contact, and a control coil. The main contact acts as the main switch that controls the power circuit. The auxiliary contact is used to control the action of the main switch. The control coil is the most important part of the contactor as it is responsible for initiating the operation of the contactor.

The working principle of the CC225/4SAD24 contactor is relatively simple. When the control coil is energized (activated by an electric signal), an electromagnetic attraction is created between the contactor core and armature. This attracts the contactor armature, closing the contactor. This in turn closes the main contact and thus completes the circuit, allowing the large current to flow through. When the control coil is de-energized, the magnetic attraction is released and the armature returns to its original position, thus opening the main contact and breaking the circuit.

In summary, the CC225/4SAD24 contactor is a popular electromechanical switch used in a range of industrial applications that require high-current switching. The contactor is composed of a main contact, an auxiliary contact, and a control coil. The working principle of the contactor is based on the magnetic attraction between the contactor core and armature when the control coil is energized. This attraction pulls the armature which in turn closes the main contact and complete the circuit.
